[0002] The sidewalk refers to the part of the road that is separated by curbs, guardrails and other similar facilities and is intended for pedestrians. Sidewalks are very common in cities, and there are sidewalks next to general streets. In some places, the sidewalks are separated from the motor vehicle lanes by grass or trees. There are relatively few sidewalks in the countryside, and sidewalk concrete slabs are used to cover and decorate the sidewalks to ensure that pedestrians are more comfortable walking on the sidewalks.

[0003] According to the Chinese patent announcement number CN219099729U, an assembled permeable sidewalk concrete slab based on the environmental protection design of municipal roads is proposed. The blind convex installed on the concrete slab achieves the effect of facilitating the walking of the blind, and the rainwater is infiltrated into the water absorption layer through the seepage holes opened on the concrete slab to achieve the effect of collecting rainwater to flow to the bottom of the concrete slab. The arrow groove opened on the top of the concrete slab achieves the effect of convenient positioning and installation. The fixed column installed at the bottom of the concrete slab achieves the effect of fixing the concrete slab in the sand. The fixed card slots installed on both sides of the reinforcement plate are docked to achieve the effect of docking and installation of two concrete slabs. When the application document is used, rainwater can penetrate quickly. When the concrete slab is installed, only the fixed card slots on both sides of the concrete slab are used for connection, which will make the connection between the concrete slabs unstable. When the sand under the concrete slab collapses, the concrete slab above it will settle with the sand, resulting in a height difference between the concrete slabs, which makes pedestrians have certain safety hazards when walking on the sidewalk. Therefore, an assembled permeable sidewalk concrete slab based on the environmental protection design of municipal roads is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-5 In this embodiment, an assembled permeable sidewalk concrete slab based on a municipal road environmental protection design includes a concrete slab body 1 and an installation component 2 installed on the top and bottom of the concrete slab body 1.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the installation component 2 includes a docking protrusion 201 fixedly installed at the bottom of the concrete slab body 1, a sliding plate 202 installed inside the docking protrusion 201, a compression spring 203 fixedly installed at the top of the sliding plate 202, a guide component 204 arranged on the left and right sides of the sliding plate 202 and ensuring its movement stability, a connecting block 205 fixedly installed at the bottom of the sliding plate 202, a connecting component 206 arranged at the top of the concrete slab body 1, and a movable component 207 arranged on the front of the concrete slab body 1 and limiting the connecting block 205.

[0034] It should be noted that the connecting component 206 includes a docking groove 2061 opened on the top of the concrete slab body 1 and adapted to the docking protrusion 201, and the inner bottom wall of the docking groove 2061 is provided with a connecting groove 2062 adapted to the connecting block 205. When two adjacent concrete slab bodies 1 are installed, the adjacent docking protrusions 201 can be installed through the docking groove 2061, and the adjacent connecting blocks 205 can be connected and installed through the connecting groove 2062.

[0035] Among them, a fixing groove is opened at the bottom of the docking protrusion 201, and the sliding plate 202 is slidably connected inside the fixing groove. The fixing groove can ensure the stability of the movement of the sliding plate 202. The top of the compression spring 203 is fixedly connected to the inner top wall of the fixing groove. When the sliding plate 202 moves upward, it is ensured that the sliding plate 202 will squeeze the compression spring 203.

[0036] In addition, the connecting block 205 is a right-angled trapezoid, and the bottom of its back side is inclined toward the front side. When the docking protrusions 201 of two adjacent concrete slab bodies 1 are connected to the docking grooves 2061 , it is ensured that the docking grooves 2061 will be squeezed by the inclined surface of the connecting block 205 .

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the movable component 207 includes a movable groove 207 opened on the front side wall of the inner cavity of the fixed groove, a sliding rod 2072 slidably connected to the front side of the concrete slab body 1 and one end of which passes through and extends into the movable groove 2071, a positioning block 2073 fixedly installed on the back side of the sliding rod 2072 and slidably connected to the movable groove 2071, a positioning groove 2074 opened on the front side of the connecting block 205 and slidably connected to the positioning block 2073, and a return spring 2075 fixedly installed on the front side of the positioning block 2073 and located on the outside of the sliding rod 2072, and the other end of the return spring 2075 is against the inner wall of the movable groove 2071.

[0038] Among them, a pull ring is fixedly installed on the front side of the sliding rod 2072. When the pull ring is pulled toward the front, the pull ring will drive the sliding rod 2072 to move toward the front, and the sliding rod 2072 will drive the positioning block 2073 to move toward the front.

[0039] In addition, the front side of the return spring 2075 is fixedly connected to the front side wall of the inner cavity of the movable groove 2071 to ensure that when the positioning block 2073 moves toward the front, the positioning block 2073 will squeeze the return spring 2075.

[0040] It should be noted that the connection block 205 can be limited by the positioning block 2073 and the positioning groove 2074 to prevent the connection block 205 from moving.

[0041] Specifically, before installing two adjacent concrete slab bodies 1, it is necessary to first pull the pull ring toward the front to disengage the positioning block 2073 from the positioning groove 2074 before installation.

[0042] like Figure 1 As shown, in this embodiment, the guide assembly 204 includes a guide block 2041 fixedly installed on the left and right sides of the sliding plate 202, and a guide groove 2042 opened on the left and right side walls of the inner cavity of the fixed groove and slidably connected to the guide block 2041. The sliding plate 202 can be guided by the guide block 2041 and the guide groove 2042 to ensure the stability of the movement of the sliding plate 202, thereby ensuring the stability of the movement of the connecting block 205.

[0043] like Figure 1 As shown, in this embodiment, a blind person convex point 3 is installed on the front side of the concrete slab body 1, and the blind person convex point 3 is used to facilitate the walking of the blind.

[0044] A water seepage component 4 is arranged on the front side of the concrete slab body 1. The water seepage component 4 includes water seepage holes and a water absorbing layer. The water seepage component 4 collects rainwater and flows to the bottom of the concrete slab.

[0045] A fixing assembly 5 is arranged on the outside of the concrete slab body 1. The fixing assembly 5 includes a fixing column and a fixing slot. The fixing column is used to fix the concrete slab body 1 in the sand, and the fixing slot is used to dock and install two adjacent concrete slab bodies 1.

[0046] The working principle of the above embodiment is:

[0047] When using the assembled permeable sidewalk concrete slab based on the environmental protection design of municipal roads, it is necessary to align the docking protrusions 201 of two adjacent concrete slab bodies 1 with the docking grooves 2061, and then pull the pull ring toward the front, the pull ring will drive the sliding rod 2072 to move toward the front, the sliding rod 2072 will drive the positioning block 2073 to move toward the front, and the positioning block 2073 will squeeze the reset spring 2075. When the positioning block 2073 is disengaged from the positioning groove 2074, the concrete slab body 1 is placed so that the docking protrusions 201 of the two adjacent concrete slab bodies 1 are slidably connected to the docking grooves 2061. When the docking protrusions 201 are slidably connected inside the docking grooves 2061, the docking grooves 2061 will squeeze the connecting block 205 through the inclined surface thereof, so that the connecting block 205 moves upward, so that the connecting block 205 completely enters the fixing groove. At the same time, the connecting block 205 will squeeze the compression spring 203, and now the two adjacent concrete slab bodies 1 can be installed.

[0048] When the two concrete slab bodies 1 are installed at the appropriate positions, the connection block 205 corresponds to the connection groove 2062. At this time, the connection block 205 moves downward under the rebound force of the compression spring 203, so that the connection block 205 is slidably connected to the inside of the connection groove 2062. When the connection block 205 is slidably connected to the inside of the connection groove 2062, the pull ring needs to be released. At this time, under the rebound force of the reset spring 2075, the positioning block 2073 moves to the back side.

[0049] In addition, when the positioning block 2073 is slidably connected to the positioning groove 2074, the connecting block 205 can be fixed to prevent the connecting block 205 from being displaced. The connecting block 205 and the connecting groove 2062 can ensure the stability of the installation between two adjacent concrete slab bodies 1 to prevent one of the concrete slab bodies 1 from sinking.
